This should be possible, but probably requires a substantial rewrite
of font.c and type-specific font drivers (xfont.c, w32font.c, etc).

Initially font cleanup at GC was introduced as a workaround for some
flaws in current font management subsystem.  See
http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00740.html

This should be possible too, but it's hard to say whether it's really
worth doing.  I just don't see a usage pattern where frames are created
and deleted often enough so any caching makes sense.
